下肢慢性静脉功能不全（chronic venous insufficiency, CVI）是国人常见的血管外科疾病。人们最早认识的是以大隐静脉曲张为代表的浅静脉功能不全。20世纪初Homans就提出治疗大隐静脉曲张的手术方式“大隐静脉高位结扎、抽剥术”，至今仍为治疗该病的经典手术方式。尽管100年来对此手术方式有所改良或改进，但手术的基本原则并未改变，即消除曲张浅静脉（不管用什么方式）以打断浅静脉返流，达到降低静脉高压的目的。......
ObjectiveTo explore the relationship among plasma cytokines’ level, adhesion molecules expression and skin damage in patients with chronic venous insufficiency (CVI) of lower extremities.MethodsIn 32 patients with CVI and 8 normal individuals as control, blood TNFα, IL1β and IL2R were assayed with ELISA method; serum endothelial cellintercellular adhesion molecule1(ECICAM1), polymorphonuclearCD18(PMNCD18) and polymorphonuclearCD11b(PMNCD11b) were assayed with immunohistochemical method; and ultrastructure of diseased veins was examined by electroscope.ResultsThe results showed that the level of plasma TNFα and IL1β increased remarkably in Class 2-3 compared with Class 1 and control (P＜0.05), IL2R had no difference in Class 1,2,3(Pgt;0.05). The index of ECICAM1 and PMNCD11b positively expression increased remarkably in Class 2-3 compared with that in Class 1 and control. The index of PMNCD18 expression in Class 2-3 and Class 1 was greatly higher than that in control (P＜0.05). The expression of ICAM1 was positively correlated with that of CD11b/CD18. Electron microcopy showed that the change in microvessel was mainly PMN adhesion with endothelial cells (ECs) and trapped in microvessels.ConclusionThe results suggest that activated monocyte may release TNFα and IL1β, upregulate ICAM1 and CD11b/CD18 expression, and mediate the PMN adhesion to ECs, thus causing ECs and tissue damage. It may be one of important mechanism of venous ulcer.
bjective To study the effectiveness of subfascial endoscopic communicating branch vein ablation in treating communicating branch vein insufficiency.MethodsFiftyseven cases of primary lower extremity vein valve insufficiency complicated by communicating vein insufficiency diagnosed by venography and color duplex were treated with subfascial endoscopic communicating branch vein ablation, and their information was analyzed retrospectively.ResultsSwelling was observed in leg of 7 cases after operation, and disappeared within one week spontaneously. Incision infection occurred in 2 cases and skin ambustion happened in 2 cases. Superficial vein varicosis disappeared in all case, skin pigmentatin declined significantly and ulcers healed in 2-3 weeks.Conclusion Subfascial endoscopic communicating branch vein ablation is an excellent choice in treating communicating branch vein insufficiency.
Objective To discuss the relationship between calf muscle pump function and chronic venous insufficiency(CVI).Methods This summarized paper was made on literature review. Results Calf muscle pump function was studied by air plethysmography,straingauge plethysmography，intramuscular pressure，calf muscle pump efficiency，foot mercury straingauge plethysmography，isotope plethysmography，and digitized photo plethysmography.The calf muscle pump function of patients with CVI decreased apparently and can be markedly improved after proper treatment. Conclusion The relationship between calf muscle pump function and CVI is apparent.
By using noninvasive venous plethysmography, venography and skin morphology, 44 patients (57 limbs) with chronic venous insufficiency (CVI) in lower extremity were studied , and compared with 12 normal subjects (24 limbs). The results showed that dermal nutrient disturbance caused by deep venous insufficiency accounted for 68%, and followed by perforating venous insufficiency was 44%. Furthermore compared venous refill time (VRT), segmented venous capacitancy (SVC) and maximum venous outflow (MVO) of dermal nutrient disturbance with those of exterior normal skin and normal subjects; and compared VRT, SVC, MVO of deep vein 3-4 stage reflux with those of 1-2 stage reflux and normal subjects,the differences were very significant (Ｐ＜0.05). Compared the VRT of perforating incompetence with that of competence (Ｐ＜0.01). Dermal pathology and ultramicrostructure showed that leucocytes trapping in capillary was a cause of microangiopathy. These results suggest that deep vein 3-4 stage reflux followed by calf perforating insufficiency was a main cause for dermal nutrient disturbance; lower extremity VRT reduced obviously and SVC increased significantly were hemodynamic character, leucocytes trapping in capillary was pathology basis of skin damage.
目的 探讨腔镜深筋膜下交通支离断术（subfascial endoscopic perforating vein surgery，SEPS）治疗下肢静脉性溃疡的效果及优势。方法 对苏州大学附属第一医院2006年12月至2008年5月期间收治的30例下肢静脉性溃疡患者（32条患肢）实施SEPS。术后观察溃疡的愈合情况及其他症状的改善情况。结果 全组随访3～15个月（平均8.5个月），静脉性溃疡于术后27～103 d(平均65 d)内愈合，湿疹消失，色素沉着逐渐变浅； 随访期间无切口感染等并发症，未见溃疡复发及新生溃疡。结论 SEPS安全有效，损伤小，并发症少，是治疗下肢静脉性溃疡较为有效的方法。
周围静脉疾病是临床上的常见病和多发病，其发病率为20%～40%，皮肤营养障碍占2%～5%［1，２］ ,发病率比动脉疾病约高10倍，发病机理比动脉疾病复杂，分类方法亦不一致，至今存在着争论。下肢慢性静脉功能不全（chronic venous insufficiency,CVI）按其病因可分为原发性、继发性及先天性; 按解剖范围可分为浅、深和交通静脉3个系统，亦即包括浅静脉曲张、深静脉瓣膜功能不全、深静脉血栓形成后遗症、交通静脉瓣膜功能不全等［３，４］。多年来下肢浅静脉曲张主张施行大隐静脉高位结扎加剥脱术，但术后复发者较多。近年来，随着国内、外学者对CVI的深入研究，尤其是对深静脉瓣膜功能不全的认识，使传统下肢浅静脉曲张的概念发生了根本转变。下肢浅静脉曲张已不再被认为是一个独立的疾病，而是一种可由多种不同病因引起的共同临床表现……
【Abstract】 Objective To discuss the role of leukocyte activation and inflammatory processes in the disease of chronic venous insufficiency （CVI）. Methods The relevant literatures about the role of leukocyte activation and inflammatory reaction in CVI were reviewed. Results The role of inflammatory reaction in occurrence and development of venous diseases has been studied a lot in recent years. It was found that the leukocyte activation and inflammatory reaction are involved in the structural remodeling of venous valves and walls, leading to valvular incompetence and formation of varicose veins. Conclusion Leukocyte activation and inflammatory processes take important roles in the occurrence and progression of CVI.
目的 评价股浅静脉瓣膜环形缩窄术治疗原发性下肢深静脉瓣膜功能不全(primary deep venous insufficiency,PDVI)的疗效和应用价值。方法 2002年4月至2006年4月期间经顺行性静脉造影加Valsalva试验证实为PDVI者119例(158条),其中2002年4月至2004年1月收治者仅行大隐静脉高位结扎剥脱+交通支结扎术(前期治疗组),2004年2月至2006年4月收治者在前期治疗方法的基础上加行股浅静脉瓣膜环形缩窄术(后期治疗组),以CEAP(clinical,etiologic,anatomic,and pathophysiologic)临床分级与临床记分评价2组的疗效。结果 2组患者术后临床分级及临床记分均明显下降(前期治疗组由5.9±3.6降至2.1±1.3,P＜0.01; 后期治疗组由6.4±3.5降至1.7±1.8,P＜0.01),且后期治疗组较前期治疗组下降程度更大(P＜0.01)。结论 股浅静脉瓣膜环形缩窄术有助于PDVI患者临床症状缓解,因此术前明确诊断为PDVI的患者,应行股浅静脉瓣膜环形缩窄手术。
ObjectiveTo compare the effectiveness of radiofrequency ablation (RFA) combined with transilluminated powered phlebectomy (TIPP) vs. high ligation and stripping (HLS) combined with TIPP in patients with varicose veins of lower limbs.MethodsA retrospective analysis was made on the clinical data of 190 patients (206 limbs) of varicose veins of lower limbs who underwent surgical treatment in our hospital from December 2017 to July 2018, of them 88 patients (96 limbs) in RFA combined with TIPP group and other 102 patients (110 limbs) in HLS combined with TIPP group. The treatment effectiveness and quality of life was assessed with venous clinical severity score (VCSS) and chronic venous insufficiency questionnaire (CIVIQ-14) in three months and one year after surgery. Doppler ultrasound was used to evaluate the closure of great saphenous vein.ResultsBaseline characteristics were similar between the two groups (P>0.05). The RFA combined with TIPP group was better than the HLS combined with TIPP group in operation time, intraoperative bleeding, hospital stay time, postoperative bed time, resumption time of activities, as well as incidences of skin induration and limb numb (P<0.05). Occlusion rates of great saphenous vein in 3 months was 93.8% (90/96) in the RFA combined with TIPP group and 97.3% (107/110) in the HLS combined with TIPP group, and in one year was 91.7% (88/96) and 97.3% (107/110) respectively, there was no significant difference between the two groups at the same time point (P>0.05). The VCSS scores and CIVIQ-14 scores also improved significantly in two groups in 3 months and 1 year follow up (P<0.05), but there was no significant differences between the two groups at the same time point (P>0.05).ConclusionsRFA combined with TIPP is an effective method for the treatment of varicose veins of lower limbs. Compared with HLS, RFA has the same good effectiveness and quality of life, but it has the advantages of short operation time, rapid postoperative recovery, and less postoperative complications.
